This invention relates to an improvement in elastic lanyards, by Which the stays of a ships rigging are connected with the chain-plate, or some iixed part of the vessel; and

It consists inthe combination of an elastic plate with the screw-bolt, and with the main packing andframes, whereby the strain upon the nut of the screw-'bolt is relieved, as will be hereinafter more fully described.

The lanyard consists piincipally of two frames, A

and B, of which the foriner is secured to the rigging or stay, whilethe latter is fastened to the chain-plate, or some other iixing on the railing or deck of the ship. The frame A consists of two or more longitudinal bars, whichare united at their upper ends, while their lower ends are fitted through a platef, and support such plate by means of nuts or heads, d, at their ends, as in iig. 1. 4

The 'ame B consists also of two or incre longitudi-y D, and' thebars B pass loosely through the plate O.

E is a central rod, iitted with its lower end into a cross-bar, c, of the frame B, and with its upper end through the plate D, carrying anut,'d, on its upper end, above the plate D, as shown.

F is an elastic bidck, or series of blocks, made of India rubber, or any other suitable material.

It lis placed around the rod E, upon the plate C, and

is covered by a plate, G, which slides loose on the rods A, B, and E.

'By means of a nut, H, which Works on the screwrod E, and which can be adjusted up or down, the greater or less degree of compression of the elastic yblock F is determined.

' There is a iiange, c, formed on the screw or rod E, somewhat below the plate D, and between this flange, or its equivalent, and the plate D, is interposed an elastic washer, f, as shown. When the rigging is strained, it will tend to pull the frame A upwards. Thereby the -plate C will be raised, and the' elastic block F will be compressed between the raised plate C and theiixed plate G. The-nut H will thus receive the whole strain, but will by'means of the ,washerf be relieved, which washer is compressed when the nutis raised by the pressure of the block F.

This elastic lanyard is strong, yielding-and of simple construction, and will operate satisiactorily.

Having thus described my invention,

What I claim as new, and desire to secure by Let-
